IMPROVEMENT IN PRINTING PRESSES.

TO ALL WHOM IT MAY conceals:

Be it known that we, JAMES'H. Fear and WILLIAM Hncnnn'r, of Sharon, in the county of Mercer, and State of Pennsylvania, have invented a new and improved Job Printing Press; and. we do hereby declare that the. following is a full, clear, and exact description thereof, reference bein making a part of this specification, in which- Figure 1 is a plan view of the press with the inking plates and a portion of the inkin Figure 2 is a top view of the inking plates.

Figure 3, sheet 2, is a longitudinal section taken in a vertical plane through the centre of the press, showing the platen thrown back from the form-bed in a position for receiving a sheet or card.

Figure 4 shows the platen in a position for making the impression.

Similar letters of reference indicate corresponding parts in the several figures.

This invention relates particularly to improvements on job or hand printing presses which have vibrating platens that are so arranged and operated as to move in the arc of a circle from an inclined to a vertical plane, the form-bed receiving, simultaneously with such movement, a reciprocating movement in a right line. The nature of this invention consists in so arranging and operating the platen, that it shall receive not only a curved movement, as hitherto, but it shall also receive a. movement up to and from the form-bed in a right line, thereby obviating the necessity of moving both the form-bed and platen in the act of taking an impression, as will lac hereinafter'described. The invention further consists in constructing the inking table of two circular plates arranged-in the same plane so as to receive rotation in diiierent directions, and to ink the roller for dilferentsized forms without wasting the ink, as will be hereinafter described.

- To enable others skilled in the art to understand our invention operation. p

In the accompanying drawings, A represents the frame of the press, which is suitably adapted for containing and Supporting the platen B, the form-bed C, and he mechanism for operating the platen and other parts necessary to be used in printing. The platen B is cons noted with four bearingar ns, a a a a, projecting irom its sides, which arms are supported and guided in slo s a a? in the sides of the press frame. Those arms which are nearest the face of the platen, and which are lettered aa, reciprocrate in the horizontal or straight portions ghad to theaccompanying drawings,

g roller removed.

, we will describe its construction, and

of the slots at, and the arms a a reciprocate in the curved portions of said slots; when the arms or bearings a are at the lower termination of'the curved portions of said slots, the platen is in the inclined position shown in fig. 1, ready'to receive upon its face the sheet to be printed, and as the platen is moved toward the form-bed G its face is brought to a position which is exactly parallel to the face of the form of type that is locked in the form-bed, as shown in fig. 4. This parallel position of the platen B is attained before the impression is made, and as soon as the arms a a 'arrive at the highest point or termination ofthe curved slot, and when the platen has attained such position it is moved up to the form in the form-bed G in a rightline. To the projecting arms a a, of the platen B, pitinan rods D D are attached, which rodsare again attached to wrist-pins or crank-pins on the sides of the crank-wheels 1) D. As these wheels are rotated they impart a reciprocating movement to the platen. It will-be observed that the arms a a do not descend into the curved portions of the slots (3 when the platen is moved back; these arms enable the'platen to be moved bodily in a right line, while the arms a a, moving in the curved portions of the slots (1 tiltthe platen from an inclined plane to a vertical plane, and vice versa. The horizontal transverse shaft D of the crank-Wheels D l) carries an eccentric, E, which is connected by means of a strap" to the bow-crank E. This crank has two toothed segments 6 b secured to it, which engage with pinion spur-WhcelSJ) b, on a rock-shaft, 6 to which rock-shaft the'slotted arms 0 c, which carry the inking roller 0 are secured. Near the lower ends of the segments 6 bis-a transverse rod, 0 which receives the upper end of the treadle rod Efland by means of this rod and the treadle E together with the fly-wheels FF, motion is imparted to the several parts of the press. The shaft F of the fly or balance-wheels F has a crank formed on it, as shown in fig. 1, to which the treadle rod E should be attached when it is desired to work the press slower than is required when said rod is attached to the segments on the bow-crank E. The treadle rod can bechanged from one crank to. another tat-pleasure for working the press fast or slow. The balancemass 2 wheel shaft F"communicates or receives motion to orfrom the shaft D by means of a pinion spur-wheel, d, engagi'ugfivith the spurred crank-wheel D, as shown in fig. 1. The form-bed C is pivoted to the crank-wheel shaft D" so that it can be thrown up to the positioii shown in red lines, fig. 4., when it is desired 'to apply the form to orreinov'e the form from it. When the form-bed is in the position shown in the figs. 1, 2, and 3 in black lines, the inking table is in a horizontal plane. The form-bed Greeeives no motion during the operation of printing, the only movement which it is allowed to receive being that above mentioned. The inking table over which the roller 0 is carried by the arms a c after every impression, consists of two plates e e". whose surfaces are in the same plane. The plate 0 is in the form of a ring and surrounds the circular plate a; both plates are supported by a central axis, e, upon a bridge-tree, G which extends transversely across the frame of the form-bed and forms a brace therefor. Both plates 0 c are allowed to turn freely, and they are rotated in opposite directions by means of pinion spur-wheels ff which turn loosely upon the cylindrical portions of thebridge tree C These pinions receivc anintermittent rotary motion from segments g g on the shaft D, 'as this shaft is revolved. The pinionfis arranged to engage with teeth on the bottom of the plate 0, and to rotate this plate in one direction, and the pinionf engages with teeth on-the plate 0 and rotates this plate in an opposite direction. By slipping the pinion f out of gear from the teeth on the ring-plate e, the plate a will only be moved; this is done when a small form is locked in the form-bed and only a portion of the inking roller- 0 requires to be inked. The ends of the inking roller pass through their slotted arms or carriers 0 c, and move in slots h it in the frame A during the passage of said roller over the surface of the type. Tire fingers ii, which holds the sheets or cards to be printed upon the surface of the platen whilst making the impressions. are connected to a transverse rod, j, which is pivoted beneath said platen, and which has crank-arms It formed on its ends, which arms are guided and moved in slots or curved guides Zon the press frame, so as to cause said lingers to be thrown from the face oi the platen as the latter recedes from the form; and then to move up to and hold the sheet upon the face of the platen, as this platen assumes a vertical position parallel to the face of the type on the form-bed, as shown by the figs. 3 and 4. p

Having thus described my invention, what we claim as new, and desire to secure by Letters Patent, is-

1. So constructing and operating the platen B that it shall move bodily in a right line up to and from the form-bed C, and also assume an inclined position when at the termination of its outward stroke, the said platen p )rforming these movements without revolving, substantially as described. I

2. Supporting and guiding the platen B by means of four bearings a a aa, which move in slots a, substantially as described. i 3. Communicating motion in opposite directions to the plates of the inking table, and also a separate and independent motion to either of the plates e e at will, all by means substantially as described.

4. Communicating motion to the rock-shaft at the inking roller arms 0 c, by means of segments 1) b, which are on a crank E that is connected to the shaft D substantially as herein described.

5. Providing for giving a rapid or slow motion to the platen and its appendages by the employment of two cranks in conjunction with the treadle and its fed, either one of which cranks will communicate motion to the shaft of the oranl -wheels D D", substantially as described.

Witness our hands in the matter of our application' for a patent for an improved printing press.
